DEVICE FOR MAKING GLASS MOL'DS AND THE LIKE.

Application ied June 25, 1921.

To all 'whom it may 00u-ccm:

Be it known that I, PETER KUCERA, a citizen of the United States, and a resident of the city of South Connellsville, in the county oi Fayette, State of Pennsylvania, have invented new and useful Improvements in Devices for Making Glass Molds and the like, of which the following is a specification.

The present invention relates broadly to devices for making glass machinery and more specially to a mechanism for automatically forming molds having co'ngurated walls. f

The principal object of the present invention is an automatic machine for shaping the interior of a mold wall in accordance with a predetermined conigurated pattern.

Another object oi the present invention is a device of the character specified and wherein the design on the mold wall is controlled by a plurality of separate pattern members.

A still further object of the present invention is a device of the character specified wherein the character of the mold wall pattern parallel to the axis of the mold is determined by a templet and the character ot the pattern circumferentially of the mold wall is determined by a plurality of individual pattern members.

A still further object of the present invention is a device of the character specified and wherein a plurality of independent pattern members are adapted to cooperate to produce the conligurated design desired.

I A further and important object of the present invention is a device oi the character specified and wherein a single tracing member is adapted to cooperate with a plurality of pattern members and wherein the contact of the templet and the plurality of pattern members is' adapted to be either consonate or successive.

Other and further objects or' the present invention will in part be obvious and will in part be pointed out hereinafter by reference to the accompanying drawings wherein like parts are represented by like characters throughout the several igures thereof.

The majority of glass ware and. particularly packers ware is manufactured in molds which are adapted to shape the exterior of the glassware. These molds may be either adaptable for pressing or blowing, dependent upon the character of ware being made.

plan'view of the secondary Heretofore in the art where any ornai'nentaprimary pat- 'I i having a smooth cylindrical wall. In the manufacture of the ordinary blocl mold adapted for pressing tluted tumblers it has requi'red a skilled workman from two to three days to produce a single mold and where a plurality ot molds were made each would diiier from the other since no two pieces made by hand are identical.

The present invention overcomes the dit- 'liculties of the known art and makesy it possible to accurately and automatically manufacture conligurated molds in accordance with predetermined patterns and wlsrerein a. completed mold may be tinished withina few hours, and where a plurality of molds are ydesired each mold is identically the same as every other mold ot the same pattern since the pattern shape and size ot r the molds are all automatically determined by the forming machine.

The present invention comprises, more specially, constructions wherein compound curves o-r a.` plurality ot individual conligurations are adapt-ed to be aiitomatically tormed on the mold body. These contigurations are all determined by a plurality oit interengaging forming members. The embodiment ot the invent-ion, which will hereinafter belde scribed in det-ail, may comprise a shaft carrying, on one port-ion the mold body to be operated 'on and another portion ot' the saine shaft carries the masterpattern or pattern plates adapted to determine the circumferential design on the mold body. This master pattern is constructed toV cooperate with the templet carried on an arm which is connected to an oscillatory head or turret on the tool bed or carriage o't' the machine and this templet is adapted to lengage an edge ot themaster pattern which rotates consonately with the mold. The teniplet is ted longitudinally over the rotating pattern plate as the tool advances into the mold .so that the longitudinal element in the pattern is controlled by the tem-plot. Where it is desired that the longitudinal element et the design shall be spiral or shall vary vin any way from a straight longitudinal line, the work taceof the templetl may be curved or variously shaped relatively to the direction ot' longitudinal movement ot the templet so that as the pattern plate revolves. and the templet slides longitudinally on the pattern plate, the work tace of the templet will engage the pattern plate sooner or later as the case may be. in the rotation ot the pattern member and mold.

The present invention also contemplates the use 'of a plurality ot pattern plates each ot which is adapted to limpose a certain t'actor ot the general conliguration usually but notnecessarily upon a Apredetermined rone in the depth or longitudinal dimension ot the mold. By this means a multiple ot lesigns may be obtained by very simple and inexpensive pattern plates and templets. These designs may be changed wholly or in part by the use ot a plurality of diierent templets with the same pattern plate or plates or by the use ot ditlerent pattern plates with the same templet.

Referring now more particularly to the drawings and more specially to Figures l and 2, the present embodiment of the invention may comprise an attachment to a lathe and the drawings illustrate certain well lmownparts oit such lathe more or less diagrannnatically. '.lhe lathe. bed l carries the usual head stock 2 in whichis mounted the main shaft el which carries the usual cone pulley that cooperates with Athe baclr gears t3. The tore-end ot the 'main shaft may be provided with a suitable holder 7 that carries the block mold body 8, or the like.

The other end ot the main shaft is also provided with a holder 9 and upon which master pattern plates l and ll are mounted. rlhe plate 10 will be referred to as the primary plate, and plate ll will be designated as the secondary plate. The inountin'g'ot these plates may be accomplished in many ways, as tor example, by spacing the plates with special blocks 1Q on carrier bolts 14 which are threaded into the holder 9. The tool carriage l5 carries an oscillatory head l@ provided with cross teed 17 on which is mounted a tool holder i8 that carries a cutting tool l). The head 1G also carries arm bracket 2O in which the control arm 2l is removably mounted. This control arm carries at the torward end an extension 22 provided with an elbow 24@ on which a templet is adapted to be mounted and to extend through the opening' in the master pat terns lO and ll.. lt desirable that arrangement be made to tend to maintain the edge ot the templet- @el in Contact with the edges oit the master patterns and to this end a bracket 2t may be mounted on the head i6 and a similar bracket 27 may be mounted on the tool carriage 1 5. A spring support bolt 28 is adapted to pass through the brackets 26 and 2T and carry on oneend the compressible spring E29 and on the other end a pair ot lock nuts 30. The action ot' the spring Q9 tends to turn the head 1G in such manner as to maintain the templet against the edge ot the openings in the patterns 10 and ll. In order to provide a stop for limiting the extent oi" turning due to `the spring` 29, a stop bolt 3l provided with a lock nut 32 mounted on one ot the brackets preferably the bracket 2'?, in such manner as to engage with a portion ot the bracket 26.

This stop bolt is adjustable and thus toi-ms a predetermined limit to the turning; movement ot' the head 16. It lis to be understood that the lathe is provided with the usual longitudinal and cross feeds and other constructions and attachments common in the art of lathes.

Referring now to Figures 3, 4, and 5, 1t will be noted that Figure 4 illustrates a glass tumbler ornamented with spiral flutings. These flutings may he either in the form of grooves or ribs. The production of the mold for the manufacture of this tumbler is accomplished by using a templet such as illustrated in Figures 3 and 5 and wherein the front or operative edge 34 of the templet is curved in the form of a spiral relatively to the length of the templet. This templet 34 is mountedon the elbow 24 when it is desired to produce a tumbler as illustrated in Fig. 4. As the cutting tool is fed .into the mold the edge 34 of the templet will travel relatively to the master plate and as the edge proceeds longitudinally relatively to this plate the contact of the configuration of the plate with the edge is either delayed or advanced, by the longitudinal movement and the spiral edge, dependent on the direction of rotation of the master plate. In exactly the same manner a relative movement of the cutting tool is retarded or advanced on the mold and consequently the path traced by this tool will be spiral so far as the longitudinal compone-nts thereof are concerned. Where the master plate is provided with a symmetric multisded opening the result will he spiral flutes and if the pattern plate has the sides of thc multi-sided opening curved outwardly the spiral members will appear as spiral grooves in the mold and as spiral ribs on the tumbler. Referring now to Figures 6, 7 and 8, it will be noted that Figure 8 illustrates a tumbler having said flutes in the form of a wide series 35 and a narrow series 36. The mold for this tumbler may be produced by the use of the two master pattern plates illustrated in Figures 6 and 7 wherein Figure 6 is the primary pattern and Figure 7 the secondary pattern, and wherein the designation of the primary pattern may be applied to the one which first contacts with the templet, and secondary as the one which contacts next with the templet. In the primary pattern 37 the edge portions 38 of the pattern are straight and the edge portions 39 are curved. The straight portions 38 determine the shape of the mold which forms the wide llutes 35 whereas the curved portions 39 form that portion which makes the cylindrical portions 40 between the upper ends of the flutes 35. The secondary pattern 41 when in place occupies the position of the pattern plate 11 in Figures 1 and 2 and as the templet 25 moves in the direction of the arrow A it will be obvious that it will engage the pattern 4l after it has been in engagement with the primary pattern 37 for some time. In the secondary pattern 41 the portions 42 are straight and the edge of the pattern plate between these straight portions is cut away as at 44. l/Vhen these pattern plates are' in position on the holder 9 of the machine the projection of the `straight edges 42 on the secondary plate coincides with the curved portions 39 on the primary plate and thecut away parts 44 of the secondary plate coineide with the straight portions 38 on the primary plate. The superposed projections of the two plates therefore is such that when` the primary pattern alone engages the temp'let the wide flutes 35 with cylindrical portions 40 between are formed on the mold wall and as the templet progresses in the direction of the arrow kA Figure 2 it begins to engage the secondary plate on the straight portions 42. AS soon as this happens the narrow flutes 36 are generated. As the tools begin to advance into the mold it is from this time on under control of both patterns,

with one pattern developing the 'wide flutes y 35 and the other pattern developing the narrow flutes 36. 4

Referring to Figures 9, 10, 11 and 12, the primary pattern 45 and the secondary pat-` tern 46 are constructed with inwardly curved sided figures and wherein the position of the curves in the secondary pattern is advanced one half the length of a side, withk reference to the position'of the curves in the primary pattern 45. lVhere these patterns cooperate with a templet as illustrated in Figure 1l a mold is produced which will manufacture Aa double fluted tumbler illustrated in Figure 12. Under these conditions the secondary pattern is provided with an opening sulficiently small to vtake the templet entirely from control of the primary pattern after the templet has progressed such a predetermined amout in its longitudinal travel as to enter the secondary templet. The result is that the master pattern 45 controls the formation of the Zone of the mold4 which. produces the flutes 48 in the tumbler 47 and the secondary pattern l46 controls the formation of that portion of the mold which forms the lower Hutes 49. p i y As further illustrating the versatility and adaptability. of the present invention, Figure 13 illustrates a templet 50 which is provided in its operative edge with cut away y portion 51. This cut away portion is constructed with reference to the distance between the location of the pattern plates at 1() and 11 so that the templet first cooperates with the primary pattern located at 10 and then with the secondary pattern located at 11 during which time the primary pattern at 10 is over the cut out portion 51. 'As the I templet 50 is moved` forward the pattern "at 10 engages the edge of the templet beyond the notch 51 and again becomes operative to control the movement of the cutting tool. The result of this type of templet when used with the patterns 45 and 46, shown in Figlob Zone 55 is a. result of theoperation of the secondary pattern 4G and the zone 56 is formed by the primary pattern e5 again being operative.

From the foregoing description it will appear thatby using a plurality of pattern plates land also by using templets having varied shaped work faces an endless variety of shapes may be imparted to mold bodies by different arrangements of the various types of templates andyplate patterns. lt will also be clear that both the teinplets and plate patterns are exceedingly simple in construction and easily manufactured and therefore these changes from one pattern to another may be made at a Very low expense.
